My files don't sync

If you find that Sync has stopped synchronizing and not all of the files are synced, there are a few things you can do.

First of all, check if peers are still connected. To do it, enable column "Peers" in UI and click the "X of Y peers" link, where X is the number of online peer, Y - is the number of peers that have ever been connected to the share. Gray peers in the list are disconnected.

If that's the case, you may need follow these steps to get your peers communicating.

If peers are connected but still not all files are synced, please inspect Sync UI a bit for any possible hints.

Check the Status column for any warnings or errors. Click on that - most of them link to explanation in KB. Inspect the files mentioned in the warning - the reason for failure to sync them is mentioned in the warning.

Check Sync History for any errors about the files syncing. Use search

Right click on a share and open peers list and check if any files are in queue for upload or download. Check the files' availability and see the most common reasons for the problem below:

- Files are filtered by .sync\IgnoreList file on all peers.Ignore list must be the same on all peers so that they all agree on what shall be skipped. Otherwise, some peers might be willing to sync the files that other peers ignore.

- Files are locked/protected by other applications. Go to the files and make sure that they are not being used by other applications, security software, encryption tools or the system itself.

- Downloading peer does not have read-write access to the files. Recheck system permissions - the user who runs Sync must have rw access to the files and the directory itself.

- Syncing between different system encoding. Check if the file names have any special symbols and check that the files are in UTF-8, the encoding that Sync understands.

-The filename or path is too long. On Mac, the max allowed character length is 1024 bytes, while on Windows and Linux it’s 255 bytes.

- Devices cannot merge folder trees. Try re-adding the folder to Sync, re-indexing this folder may be required. You can do this by simply removing the folder from Sync and adding it back.

- If Sync encounters file system errors it will abandon syncing. We advise running a disk check and searching for bad hard drive sectors. Also, it's a good idea to see if all drives are mounted properly.

- Sync doesn’t receive notifications about file change. Try restarting Sync so that it rescans the folder, or "touching" the files.

- The device that is downloading has run out of free space. Try making some room on the device/drive that is nearing max capacity or designating a different drive for the synced folder.
